摘要
采用正交实验法研究6061铝合金铸锭均匀化处理工艺,通过金相显微镜、维氏硬度计对其均匀化处理效果进行定量观测、评价。实验结果方差分析表明,其加热温度对相转化率有高显著性的影响,温度越高相转化率越大,600oC时相转化率可达72.4%;冷却方式对硬度有高显著性的影响,冷却速率越快硬度越大,水冷时的维氏硬度可达HV0.181.4,其他工艺参数对上述两项指标的影响均不明显。
The homogenization annealing process of 6061 aluminum alloy ingots was studied by orthogonal test. By means of metallographic microscope and Vickers hardness tester, the effect of homogenization annealing was observed and evaluated quantitatively, and variance of experimental results was analyzed. It is found that heating temperature has a high significant effect on the phase conversion rate.The higher the temperature is, the higher the phase conversion rate will be. At 600℃, the phase conversion rate can reach 72.4%. The type of cooling has a highly significant effect on hardness. The higher the cooling rate is, the greater the hardness will be. The Vickers hardness HV0.1 can reach 81.4 with water cooling. Other process parameters have no obvious influence on the above two indexes.
